Abstract

The invention provides a dual-mode vehicle-mounted radio station system, and the system comprises a first communication module which is used for achieving the GSM-R network communication; a second communication module which is used for realizing LTE-R network communication; and a selection control module which is used for controlling the system to select the first communication module or the second communication module for network communication. The first communication module and the second communication module are respectively powered by an independent power supply. The first communication module and the second communication module respectively employ standard chips and are combined with a peripheral circuit to realize GSM-R and LTE-R network communication. The first communication moduleand the second communication module perform data transmission through the same antenna unit; and the peripheral circuit comprises a signal conversion circuit arranged in the second communication module, and the signal conversion circuit is used for converting LTE-R network communication signals to a specified range and transmitting and receiving the signals through the antenna unit. The dual-moderadio station is wide in application range, low in cost and high in flexibility.

Description

technical field [0001] The invention belongs to the field of rail transit communication, in particular to a dual-mode vehicle-mounted radio system. Background technique [0002] At present, high-speed railway trains mainly use on-board radios based on the C3 train control system. By the end of 2016, there were 1,200 EMUs with a speed of 300km / h. With the development of communication technology, the development trend of railway digital mobile communication system from 2G system to 4G system is more and more obvious, and the original GSM-R radio station can no longer adapt to this change trend. High-speed trains need to run on a line consisting of a part of the GSM-R communication network and a part of the LTE-R communication network. Therefore, a station that can support both GSM-R communication and LTE-R communication is needed to solve CTCS-3 / 4 Vehicle ATP communication problem. [0003] In the prior art, there is a technical solution for installing two independent radio...
